You can easily create services by creating an application that is installed as a service. For example, suppose you want to monitor performance counter data and react to threshold values. You could write a Windows Service application that listens to the performance counter data, deploy the application, and begin collecting and analyzing data.

you'll notice all of the Service Contracts are implemented with interfaces containing only methods. For the longest time I thought that's all that was supported, until I thought about it a little more. In C# land, properties are simply wrappers around a get method and set method, so why wouldn't we be able to use properties in a service contract? Well the answer is we can.

This article is meant to be a practical discussion guide to building a .NET application in a service-oriented architecture. We will consider real-world goals, real-world obstacles, and experience-based solutions. I quickly concede the approaches discussed here are not exhaustive or infallible. This paper is focused on application development, not application integration. We will specifically consider architectural issues and component design issues.

WS UploadService is a web service written for Microsoft Office SharePoint Server 2007 and Windows SharePoint Services 3.0 and is meant for uploading documents into SharePoint. I have just uploaded the zip file to GotDotNet.com so it will take some time before the zip file appears in the list of downloads. For the time being, you can download the zip file from the following location

In addition to letting you create Web pages, Microsoft Visual Studio also lets you create Web services that use ASP.NET XML. Creating a Web service in Visual Studio is similar to creating a Web page. You can also use the Microsoft Visual Web Developer Web development tool to reference and use Web services that are in a Visual Web Developer solution, on your local computer or in a local or external UDDI directory. In this walkthrough, you will create the Web service in one solution and use it in another.

I'm creating a Dynamic Data application in VS2010 and have recently
switched to using a Domain Service to give greater control over the
data presented to the client. I've noticed that the
AutoGenerate<Action>Button attributes on my GridView are being
ignored. The presence of the Edit and Delete buttons appear to be
contingent on the existence of Update and Delete methods on the partial
classes autogenerated in the Domain Service, but i'm not seeing how to
control the generation of the Select button. Is there a way to control this from
within the Domain Service class?

Just curious to know if there was any official Microsoft code blocks, classes, or such for writing a service that runs other assemblies or WCF services? That can be configured easily from a web page, pre-coded, for running tasks at certain times on certain recurring intervals? I've already built one but am open to anything done better- which I'm sure there is. Thanks!!!

One server with Windows 2003, hosting the web service using .Net Framework 2.0, with IP 10.0.2.50 and host name ServerTransaction.Other server with Windows 2003, hosting a web application using .Net Framework 2.0, that consuming the web service on ServerTransaction, with IP 10.0.2.51 and host name ServerApplication.Many other computers on the local network (IPs: 10.0.2.80, 10.0.2.81, 10.0.2.82, ...) acessing the web application on ServerApplication.

On the code of the web service I've tried to use HttpContext.Current.Request.UserHostAddress or HttpContext.Current.Request.ServerVariables("REMOTE_ADDR") or HttpContext.Current.Request.ServerVariables("HTTP_X_FORWARDED_FORR"), but always I can only get the IP of ServerApplication (10.0.2.51).

Hello,
I've built an ASP.NET web service with .NET 2.0 (an asmx file). I invoke a web service method using Ajax. The method takes a substantial amount of time to execute (5 minutes to 1 hour). I believe it's not a good idea to "hang" the web request for so long.

I'm wondering if the web service method could spawn an additional process which in turn would execute the lengthy operation and notify the web service once the operation is completed.

Are there any good practices regarding this kind of functionality?
Thanks,
Leszek
